5.2 IT8368E Configuration
5.3 SED1355 Configuration
Interfacing to the Philips MIPS PR31500/PR31700 Processor
Issue Date: 99/05/05
The ITE IT8368E has been specifically designed to support EPSON LCD/CRT controllers.
Older EPSON Controllers not supporting a direct interface to the Philips processor can
utilize the IT8368E MFIO pins to provide the necessary control signals, however when
using the SED1355 this is not necessary as the Direct Connection described in Section 4,
“Direct Connection to the Philips PR31500/PR31700” on page 9 can be used.
The IT8368E must have both “Fix Attribute/IO” and “VGA” modes enabled. When both
these modes are enabled a 16M byte portion of the system PC Card attribute and IO space
is allocated to address the SED1355.
When the IT8368E senses that the SED1355 is being accessed, it does not propagate the PC
Card signals to its PC Card device. This makes SED1355 accesses transparent to any PC
Card device connected to the same slot.
For mapping details, refer to Section 4.3, “Memory Mapping and Aliasing” on page 11. For
further information on configuring the IT8368E, refer to the IT8368E PC Card/GPIO
Buffer Chip Specification.
For SED1355 configuration, refer to Section 4.2, “SED1355 Configuration” on page 10.
